Abstract
Poor link quality that may occur from environment factor such as noise and fading drops the Signal-to-Noise Ratio (SNR) value. This contributes to packet loss during the packet transmission in wireless networks. The objectives of this thesis are to re-design existing MAC protocol to support piggybacking by inserting SNR field in the RTS-CTS frames. It is also to evaluate the protocol performance in terms of average delay and throughput. Non-persistent CSMA has been used as the access protocol and Rayleigh fading channel is chosen as the channel model. As we discovered, WCN with piggybacking mechanism does improve the link quality and hence increase the throughput performance by more than 3 times compared to normal WLAN.
